Hello,
I have developed a project with Xampp and PHP 7.2. I have updated to PHP 8 and the project broke. Meaning that I get a 404 error. If I toggle across PHP versions I see that up until PHP 7.4.20 everything is fine. But as soon as I switch to PHP 8 (8.0.7 to be precise) everything breks since CI is not able to access any page anymore. I only see my custom-made 404 page. Has anyone experienced this problem? If so, how to solve it? Thanks

Using PHP 8.0.7 and CodeIgniter 4.1.3, it's working without any issues on my side?

ok, I will update my CI4 version then. Thanks for the feedback guys
Hello, sorry to bother again. I was reading the documentation to update from version 4.0.4 (the one I have) to the latest one but am a bit confused on how it should be done (never upgraded versions before). Can you please help on the steps needed to upgrade? In the documentation they describe many changes but would not know how to implement them manually. Or should I just reinstall CI4 from scratch? Thanks

Basically, copy the changes from /vendor/codeigniter4/ to your project while keeping your own changes intact. The upgrade documentation should list the files that have been changed.

Thanks for the reply but what do you mean "copy the changes from /vendor/codeigniter4/"? Where do I get these changes from? Thanks for whatever help you can get

@AndreaL be sure that you read the general upgrade instructions before you dive into the “Upgrade from 4.x to 4.y”. These instructions are specific to your installation method so can be found on each of those pages. I.e. for Composer installations: https://codeigniter.com/user_guide/insta...#upgrading
